Where MDR1 applies

Polygons and hectares by the Town of Halton Hills’ outlines, each polygon placed by a point inside it. 35 zone polygons fall outside every outline.

Exceptions, holding and other markers

The markers the layer records on MDR1 polygons. Their terms are written only in the by-law; each line says where.

Site-specific exception (15 polygons)
31 (×3), 100-A (×2), 3, 73, 74, 84, 85, 100-B, 100-C, 100-D, 108, 111Section 2.5: a number in brackets after a zone symbol refers to a site-specific exception listed in Part 13.
Holding provision (2 polygons)
H17 (×2)Section 2.6: where a zone symbol is followed by (H), no use other than the existing one until the (H) is removed; holding zones are detailed in Part 14.

What the zone permits

The permitted uses and regulations for MDR1 are set out in Part 6 of Comprehensive Zoning By-law 2010-0050 (PDF, Town of Halton Hills). HaltonHillsIQ does not paraphrase them: an exception, a holding provision or a later amendment can change what applies to one lot. The Town of Halton Hills’ Compliance Memo Request is the Town of Halton Hills’ own answer for a property. The interactive zoning map shows the zone on a single lot.
